Two stretches of water with glacial origin. You can reach them from Passo Rolle, after a nice walk across Paneveggio Forest, or from San Martino Malga Ces. The landscape is typically alpine rather than dolomitic: as a matter of fact, the area faces Lagorai. Already 8,000 years ago, Mesolithic hunters used to visit these places leaving their tracks through some manufactures discovered thanks to the archeological excavations.
